Wow, that’s crazy. I’m Australian (Australian Dad & Kiwi Mum) but I actually have Irish in my heritage. I am also the only one in the family to have red hair which was apparently a massive coincidence only possible because of DNA that by chance was on both my Mum’s side and my Dad’s side (I don’t know the fine details). Until I was 13-14, my eyes used to change colour between Green and Blue depending on the time of year. Now I’m approaching 23 and my eyes have consistently been green since around 14.
